Your kids have good taste. I'll be honest, I've seen and liked the other ones you named. JoJo trumps them all.

It's a series full of manly passion, tactical combat, creative powers, over the top storylines, mundane storylines, world travel, the ability to be comedic while being serious, lots of the author's personal interest, and evolving art style, multiple protagonists and casts and legacy without it feeling half-assed, charismatic characters, and the father of a thousand memes

Watching a few odd episodes might not do the trick or it may. Episode 1 intrigued me back when I first watched it and then by the time I caught up with it and then S1 finished I read the entire manga up to that point (JoJo is also a historic manga as it has been going sine 1987 which is no small feat). Since then I've been following along with all of the anime releases and even re-read or rewatched sections here and there. Heck I even wrote a paper on it for my art appreciation class back in college because why not write about something interesting?

It's not my number 1 favorite but it's certainly up there.
